Installation, Portable Powered Scoreboards...................................... Drawing A-1039104
For locations where a power source may be unavailable or an outdoor receptacle difficult to
reach, the track displays can be connected to an optional portable power pack. A portable
power pack permits operation of a small display via battery power. The power pack is
provided by customer and should include batteries, a charger, and a 120 VAC power
inverter. Daktronics has a hookup kit available (part # 0A-1192-0349) for a customer-
provided battery pack. Refer to Drawing A-1039104 in Appendix A for installation steps.
4.2 Signal
As noted previously, models TI-2020 and TI-2021 are self-contained and require no external
signal connection or controller. However, both units may be operated directly with an All
Sport controller or as part of a complete Daktronics scoring/timing system. The signal
information in this section applies only when an external controller is used.
Drawing A-178820 and Drawing A-305729 in Appendix A illustrate the signal connections
on the end panel of each display. Begin signal installation by routing conduit and cable
between the display location and the control location. Use paired, shielded cable, 22 AWG
minimum (part # W-1077), and connect the cable to a junction box at the control end. Attach
a
1 /
4
" phone plug to the display end of the cable. Insert the plug into the jack (J31) on the
display‟s side panel. Connect a signal cord between the control J-box and the controller. The
timing displays are shipped ready to operate, so the signal installation requires no internal
connections or changes.
